Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically to a solution for fixing a top cover without a rear fixing screw. Background Technology

[0002] In existing technology, during the installation of an air conditioner outdoor unit, the left rear side of the top cover is typically fixed to the upper part of the left side panel with screws, or the left rear side of the top cover is not fixed to the upper part of the left side panel without screws. However, both solutions have problems. And these problems have plagued the air conditioning industry for nearly a century without being effectively resolved.

[0003] When the rear left side of the top cover is not fixed to the upper part of the left side panel, the outdoor unit of the air conditioner is typically hoisted outdoors using a rope threaded through the gap between the top cover and the left side panel, and then lowered to the installation position using the rope. See details... Figure 1 In this situation, the entire outdoor unit of the air conditioner, weighing tens of kilograms, is held in place by a single screw that secures the left end of the top cover and the left side panel (the screw is not shown in the picture). If this screw strips, the outdoor unit of the air conditioner will fall from a great height.

[0004] When the top cover is fixed on the left rear side and the upper part of the left side panel, during later maintenance of the outdoor unit, because the gap between the outdoor unit and the wall is very small, see details... Figure 2 The dimension L in the screwdriver is usually smaller than the length of the screwdriver, resulting in insufficient space to remove the screw and making repairs inconvenient.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-8 As shown, a solution for fixing a top cover without rear-side fixing screws includes the following steps:

[0036] S01. First, put the top cover 100 down from top to bottom, then slide it to one side so that the symmetrical protrusions 110 on one side inner wall of the top cover 100 are locked onto the abutment 210 on one side side wall of the left side plate 200.

[0037] S02. The top cover 100 and the right side plate 400 are assembled using multiple stepped screws 300, wherein:

[0038] The left side panel 200 and the right side panel 400 are arranged opposite each other.

[0039] Specifically, in step S02 of the above embodiment, the threaded end 310 of the stepped screw 300 is threadedly assembled with the threaded hole 410 on the right side plate 400. This allows the first pressing surface 340 of the stepped screw 300 to abut against the outer side surface of the right side plate 400, and the bridge seat 330 of the stepped screw 300 to abut against the outer side wall of the top cover 100. The threaded assembly of the stepped screw 300 provides side locking, preventing displacement of the top cover 100 and ensuring the snap-fit ​​engagement between the boss 110 and the abutment block 210.

[0040] In the above technical solution, the boss 110 on the top cover 100 is engaged with the outwardly protruding abutment 210 on the left side plate 200 to secure the left rear side of the top cover 100. Figure 2 and Figure 4 ) and the upper part of the left side panel 200 ( Figure 5 This method ensures the strength of the area without using screws for fixing, thus guaranteeing both installation safety and ease of maintenance and disassembly.

[0041] As a further embodiment of the present invention, such as Figure 6 As shown, the cross-section of the abutment block 210 is a right-angled trapezoidal structure, and the lower base of the right-angled trapezoidal structure is connected to the left side plate 200, with its inclined surface facing downward and maintaining a sliding connection with the boss 110.

[0042] Furthermore, the side of the boss 110 that contacts the inclined surface is a plane.

[0043] Furthermore, a first screw hole 120 is provided on one side of the top cover 100, which is arranged opposite to the boss 110;

[0044] The stepped screw 300 includes a smooth rod 320, and the radius of the first screw hole 120 is slightly larger than that of the smooth rod 320.

[0045] Furthermore, the length of the first screw hole 120 is equal to or slightly less than the length of the smooth rod 320.

[0046] The width between the end face of the boss 110 and the inner wall of the top cover 100 is greater than the length of the smooth rod 320.

[0047] Specifically, in the above embodiment, when the top cover 100 is placed on the machine body, it is pushed from the side of the boss 110 towards the side of the threaded hole 410, causing the boss 110 and the abutment 210 to engage. This ensures that the top cover 100 slides normally to the corresponding positions of the left side plate 200 and the right side plate 400 without causing interference.

[0048] As another embodiment further provided by the present invention, such as Figure 7 As shown, the stepped screw 300 includes a threaded end 310, a smooth rod 320, a bridge 330, and a first pressure surface 340;

[0049] One end of the smooth rod 320 is a threaded end 310, and the other end is a bridge seat 330;

[0050] The first pressing surface 340 is the mating surface between the smooth rod 320 and the threaded end 310;

[0051] The radius of the first pressure surface 340 is smaller than the radius of the bridge seat 330.

[0052] As another embodiment of the present invention, the top cover 100 is removed in the reverse process of installation. First, the stepped screw 300 is loosened and removed from the right side plate 400. Then, the top cover 100 is slid to the right so that the inward protruding boss 110 is completely disengaged from the outward protruding abutment 210 of the left side plate 200. Then, the top cover 100 is removed upward.

[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
